ASLP 5825 Speech Production Analysis Types

Independent Analysis

Goal is to describe what the child can do, regardless of errors; focus on phonetic inventory, syllable inventory, word shape (length — mono, di, poly syllables), stress patterns

Relational Analysis

Goal is to compare the child’s production to the adult model’s; measured by % correct

SODA Analysis

Error analysis; measured by the number of errors divided by the number of opportunities to produce the specific sound

Analyses of Phonological Processes — Syllable Structure Process

Any changes to syllable structure

Analyses of Phonological Processes — Substitution (Systemic) Processes

Changes to the consonants or vowels in words; the change usually involves a feature of a phoneme rather than an entire (individual phoneme)

Analyses of Phonological Processes — Assimilatory Processes

One sound becomes more like another sound in the same word = complete or partial? contiguous or noncontiguous? progressive or regressive?

Phonological Mean Length of Utterance (pMLU)

Total Phonemes Produced / Total Words Produced

Percent Whole Word Proximity (PWP)

Number of Correct Phonemes in a Word / Number of Phonemes in Adult Target x 100
